Now when you pave a concrete driveway, traditionally you will use a soil or road base to grade the material. You can use wire mesh or steel rebar to hold it all together and make it bond strongly. When making concrete, it is a bag of sand and gravel, cement, dry ash, and chemical-add mixtures to help actually reduce the water content which makes for stronger concrete. Ready mix concrete is concrete that is batched at the concrete plant into a concrete truck and delivered to the job. There's no difference between ready mix and regular concrete. Wear safety goggles, hard hats, rubber gloves, rubber boots, long sleeves, and pants. Shorts are not a good idea.
